Modular mattress assembly

ABSTRACT

The modular mattress designed to be easily assembled. The mattress assembly includes a double-border wire unit having a central cavity. The cavity is adapted to receive a matrix of coil spring units therein. The coil spring matrix is removably attached to the double-border wire unit. Foam rubber forms are inserted into the wire unit to form the perimeter of the mattress without using glue or similar fastening means.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to bedding construction, andparticularly to a modular mattress assembly that has easily assembled,modular mattress components, including a double border wire unit forreceiving a coil assembly therein.

2. Description of the Related Art

Mattresses are conventionally constructed with a central portion or coresurrounded by a border structure. The core is generally fabricated froma matrix of coil springs covered by a quilted fabric. Other coreassemblies may comprise polyurethane, air or water bladders, latex orother synthetic material. Conventional border structures comprise asemi-rigid frame, often fabricated from foam rubber, to which the coreis attached with glue. The assembled mattress is unwieldy, and thereforedifficult for the average consumer to handle and transport. Thebulkiness of the assembled mattress also creates shipping problems tothe extent that anti-dumping regulations are violated if exported tosome countries. A modular mattress assembly having compact andeasy-to-handle components would certainly be of benefit to the beddingindustry and consumers. Thus, a modular mattress assembly solving theaforementioned problems is desired.

SUMMARY OF THE INVENTION

The modular mattress assembly comprises modular mattress componentsdesigned for easy assembly. The mattress components include adouble-border wire unit having a central cavity. The cavity is adaptedto receive a matrix of coil spring units therein. The coil spring matrixis removably attached to the double-border wire unit. Foam rubber formsare inserted into the wire unit to form the perimeter of the mattresswithout using glue or similar fastening means.

Accordingly, the invention presents a mattress having modular featuresto enhance shipping and/or transporting thereof. The modular componentsare easy to assemble and include foam rubber segments that form theperimeter of the mattress. The invention provides for improved elementsthereof in an arrangement for the purposes described that areinexpensive, dependable and fully effective in accomplishing theirintended purposes.

These and other features of the present invention will become readilyapparent upon further review of the following specification anddrawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1-3, the modular mattress assembly 10 comprises adouble-bordered wire modular unit having vertically-spaced top andbottom (or upper and lower) members. The top member comprises respectiveouter and inner border wires 12, 12 a that lie in the same horizontalplane. The inner wire 12 a is laterally spaced from the outer wire 12.The bottom member is a mirror image of the top member, having respectiveouter and inner wires 14, 14 a. A plurality of C-shaped wire fasteners18 is employed to attach members 12 to 12 a and members 14 to 14 a. Thetop and bottom double-bordered members are adapted, when assembled, tobe spaced apart vertically, establishing the periphery of the assemblyand defining a cavity in the center thereof. Although illustrated asrectangular, it should be recognized that the double-bordered top andbottom members could be designed in other configurations (circular,hexagonal, octagonal, etc.), and in various sizes. A matrix of coilspring units 16 defines a modular unit that is adapted for insertioninto the cavity to form the central portion of the mattress assembly. Aplurality of fasteners 19 are employed to attach the inner border wires12 a, 14 a to the coil spring unit 16. Semi-rigid segments 20,preferably fabricated from foam rubber, are removably inserted into thevertical space between the top and bottom double-bordered members todefine the perimeter of the assembled mattress and to provide stabilityand support for the assembly. The segments 20 are non-adhesivelyretained between the upper and lower members, e.g., by a pressure orfiction fit between the double-border wire units of the top and bottommembers.

It is to be understood that the present invention is not limited to theembodiments described above, but encompasses any and all embodimentswithin the scope of the following claims.
